My feature key is lite and I have DND. How do I get this to cancel

Remove the Line wire from the back of the phone and then plug it in again. See if the DND function is still on. If yes : pick up the handset or press Speaker key and then press the corresponding DND Softkey (the buttons right under the LCD). If you don't see any DND text on the LCD of the phone try to move to another pair of Softkeys by pressing the last button (see the >> on the LCD)

Here is a link to the manual. The link has it as IBM and IBM-412CID, but they are the same phones! Bell Equiptment and IBM both sold the 412CID under their names, no difference.

Office phone, IBM-412CID, had power failure, reset phones, now cannot remove DND without constant ring

Must reset all extensions with individual extension numbers after a power outage. Just the same as starting the phone out of the box. Thanx.

No ringer


I would suggest unplugging the phone from power and the phone jack for about 5 minutes and see if that will clear the DND LED.

Here is a link to the manual.

Please refer to Pg 38 specifically for disabling DND.

412 cid phone

The picture here is of a Comdial phone I am familiar with but that is not what you are describing. I am not familiar with your specific phone but it sounds like you have the phone in headset mode. There may be a button to turn this feature on/off that was hit by mistake.
